10- Claims- 'My-invention relates to fliers of the type used withspinning machines, and more particularly to a novel flier block arrangement having. im proved means for attaching and supporting the flier wire and the flier wire balance.

Conventional flier blocks are generally adapted for use with either single or double armed flier wires. In the use of wires which'are symmetrically arranged'with respectto the block, that is to say, when the arms of the wires extend outwardly on opposite sides of the flier block, the 'flier remains in a substantially uniformly bal anced condition during its rotation about the bobbin spindle. V tions it isdesi'rable' to use a single flier wire having the arms thereof projecting from the same side of the block It will beapprec'iated that in the use of wires arrangedln" this manner, that means must be provided to balance 'the'flier and more particularly to overcome the unbalanced forces set up by the wires when "the'blockis rotated.

Heretofore it has been proposed to provide fliers comprising a plurality of separate parts or elements constructed and arranged to inter-lock whereby to form a complete flier. It has also been proposed to eifect balancing by attaching a member in the form of a wire loop, or other bail-like device to the block on the side oppo site the flier wires. In Patent 2,187,862, for'eiiample, issued to me on January 23, 1940, there is disclosed a flier construction" having a flier wire support member in the form of a plate adapted to flt over the head portion of the flierbody or block, the plates'being attached to the flier body by means of a cap positioned below the plate and attached thereto by spot welding; also in Patent 2,259,826, issued to me October 21, 1941, there is disclosed a flier construction wherein the block is designed to receive a balancing member,

arranged to compensate the unbalanced forces due to projection of the flier wire arms on the same side of the block.

' The present invention relates to a flierof the general. type disclosed in the aforementioned patcuts, and more particularly to a counterpoised flier block witha single flier wire and a counterbalance therefor. After considerable research and experimentation, I have found that'the flier constructions of the type disclosed in my prior patents, and other constructions exemplified by prior art arrangements comprising multi-part blocks, can be substantially sir'n'pl'ifled to provide improved operation with marked economies in manufacture. a

Under certain winding'condi (o1. s'rsi.

Another object of my invention to provide a flier' construetionhaving improved means, for

V attaching and supporting a flier wire thereon.

Yet another object of my invention is to pro-. vide'an improved flier wire balance. 7. 7

Still another'objeetof my invention is to pro: vide a flier wire balance which may be quickly; attached to or removed from av flier block.

- A further object of myainventionis. to provide a detachable flier wire balance which can be: applied to or removed from a flier blockwithout the use of specialtools or implements.

Yet another object of my invention is the provision of a counterpoised, flat flier'mounting a single flier wire, and held in operative position on a capped'bobbin spindle by a superposed weight.""

It'is also an object of my invention to pro! vide improved flier wire balances which are self seating and self-locking; I

With these and other objects in view, which may be incident to my improvements, the 'inventioflri' consists inthe parts and combinations tdbdhrinafter set forth and claimed, with the understanding that the several necessa y e ements; comprising my invention, may be varied'in construction, proportions and arrangement's, without departing from the spirit and scope' of'the appended claims. l

Inprd'er to make my invention more clearly understood, I have shown in'the accompanying drawings means for carrying the same into practical efiect, without limiting the improve-- ments in their usefulapplications to the par-2 ticular constructions, which for the purpose of explanation; have been'made the subject 'of..il1ustration.

In' the drawings? Figure 1 is an "elevational view, partlyin sec: tion, showing aflier equipped with my improved balance, inithefioperative position on a bobbin spindle. H V

Fig. 5 is a perspective elevated view "of the modified form of flieri balancefshown in.Fig;f4; -Fig. 6 is a perspective view of the top of a bob- The proposed form of flier construction of the present invention, comprises essentially, a generally flat, flier block, in the form of a centrally apertured body member having diametrically opposed flier Wire support members and flier wire balance support, said supports being substantially counterpoised. The flier wire support comprises a transversely apertured lu'g offset from the head portion and an aligned hook member mounted adjacent the periphery of the flier. The counterpoised section of the flier body comprises a generally rectangular thickened body portion, the top surface of which is slotted or apertured to receive the spring-biased arms of a generally rectangular flier wire balance. In assembling the flier, the flier wire balance is snapped in position, and the flier wire is locked in place, after which the flier is inserted over the spindle with the eccentric foot positioned in locking engagement in the ferrule of the bobbin.

Referring to the drawings, and more particularly Fig. 1, there is shown a flier arrangement associated with a bobbin I, mounted in operative position on a suitable spindle 2, of a conventional winding machine. The bobbin is provided with a head member 3, and a centrally recessed portion 4, adapted to receive a ferrule 5, having an aperture 6 through which the flier foot of the block 8 is inserted. The flier block 8 comprises an upper body section 9, and a depending tubular section ||l, provided with the foot I, as previously described. The body and tubular sections are provided with a central aperture desirably tapered, and adapted to fit over the spindle 2 of the bobbin. The body section is also provided with an offset lug |2, having a transverse aperture l3. The flier body includes a depressed lateral platform section |4, tapering toward the edge and thickened on the under side, as indicated at |5. Adjacent the edge l5, there is provided an angular locking lug |5 adapted to receive the section 2| of the flier wire in locking engagement. Diametrically opposed to the platform I4 is the generally rectangular, counterpoised section |6, having its central body section 3 provided with a depressed offset section II,

forming a platform l8 for the flier wire balance. 5

tion 2|, having its forward end 22 bent at right angles, and terminating in the thread-receiving loop 23. The rear end of the flier wire is laterally offset at a slight angle as shown at 24, and is bent on itself to form a horizontal cross bar 25, having its end 26 bent at a slight angle. The flier wire is mounted in place by inserting the transverse leg section 25 through the aperture |3 in lug l2, and springing the section 2| laterally to clear the locking lug |5, the section 2| of the flier wire being slipped in place under the locking ing, and spring-biased therein. in locked position.

The flier wire balance 30 is of generally rectangular shape, and comprises a pair of spaced parallel arms 3|, 32, joined by cross bar section 33. The forward ends of the legs 32 are bent inwardly, as shown at 34, 35, and then forwardly, as shown at 36, 31, the ends 38, 39, being bent inwardly at right angles. As shown in Fig. 3, the member 30 and the legs 3|, 32, are normally spring-biased to flare outwardly in the unrestrained, inoperative position. In the operative position, as shown in Fig. 2, the legs 3|, 32 are apposed, and the segments 36, 31, are fitted in the undercut slots IS, with the ends 38, 39 fitted in the transverse slot 20, whereby when the pressure is released, the spring-bias of the legs 3|,

' of the unit.

32, positively seats the locking sections 36, 31, and 38, 39 in their respective seats.

In the form shown in Figs. 4 and 5, the flier is provided with a pair of spaced, transverse apertures 4|, 42, adapted to receive the locking members of the modified flier wire balance 40, which will now be described. The member 4| comprises spaced, parallel arms 43, 44, joined by cross bar section 45, and terminating in inturned end portions 46, 41 which are generally parallel to section 45, and are mutually displaced by an amount equivalent to the spacing between the apertures 4|, 42 in the flier block. Referring more particularly to Fig. 5, it will be seen that in the unrestrained position, the legs 43, 44 are spring-biased inwardly toward each other. When the member 40 is mounted in place on the flier block, the legs 43, 44 are sprung apart and the end sections 46, 41 are inserted in the apertures- 4|, 42, being locked therein by the spring-bias It will be seen that the flier wire balance 30, shown in Figs. 1, 2 and 3, is maintained in substantially rigid position, while in the form shown in Figs. 4 and 5, the member 40 may be displaced upwardly, under applied pressure, but will spring back into its normal, flat, seated position when the biasing pressure is released.

In Fig. 6 there is shown a plastic flier body 50 for use with large bobbins. In this form of the invention, a bobbin 60, having a head portion 6| is mounted on an oversize spindle 62, which is provided with a millnut 63 at the top thereof. The plastic flier body 50 is comprised of a generally flat body portion 5|, having a tapered forward end 52, slightly thickened as shown at 53,.a generally rectangular rear platform section 54, having a slightly thickened portion 55. A centrally apertured ring section 58 surmounts the top of the flier body, and is provided with a forward,transversely apertured lug 5'1, corresponding to member l2 of the other flier bodies, and a locking finger 58, corresponding to member I5. It will be noted that in this construction, the flier wire 20 is locked in place in the usual manner, but is not counterbalanced. An annular weight 64 is fitted over the spindle 52 and rests on the upper surface of section 56 of the flier body. The millnut 63 restrains the weight 64 from any upward movement sufiicient to permit it to ride up land ofi of the top of the spindle.

In Fig. 8, there is shown a metal flier body 70, having the usual generally flat body section 1|, a tapering forward section 12, formed with depending thickened section 13, a rectangular rear platform section 14, having a depending thickened section l5. The centrally apertured collar 16 has an opening of a diameter corresponding to the openings II of the fliers of Figs. 1, 2 and 4. A transversely apertured lug 11 is formed on the forward side of member 16 and armor-v cooperates with looking. finger 18 to holdthe: flier wire '20 in locked relation,

It will be seen that with the improvements of the present invention, when a single. flier wire is used, the loops 38 and 40, serving as flier wire balancing members, will balance out the contrifugal forces generated by the flier wire when the flier block is rotated, thus providing uniform tension on the yarn. Similarly, by theuse of weight 64, the desired tension or .drag on the yarn can be obtained, 1 I

While I have shown and described the preferred embodiment of my invention I wish. it tobe understood that I do not confine myself to the precise details of construction herein set forth by way of illustration, as it" is apparent thatmany changes and variations may be made therein, by those skilled in the art, without departing'from the spirit of the invention, or exceeding the scope of the appended claims.
